Letters Patent No. 81,575, dated September 1, 1858.

IMPROVEMENT IN MACHINES FOR MAKING BARRELS.

TO ALL WHOM IT MAY CONCERN:

Be it known that we,VSAX'10N J. ARNOLD and AMoS F. CLARK, of Raymondsville, in the county of St. Lawrence, and' State of New York, have invented a new and useful Improvement in Machinery for Turning and Finishing Barrels; and we do hereby declare that the following is afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of this specification. I p

This invention relates to an improvement in machinery for turning and finishing barrels, and consists'of a device for holding the barrel in a convenient position for the eonductof these operations.

In the accompanying drawings- Fig-ure l1 is a vertical section of our improved device, showing one of the nuts in side view, and

Figure 2 is an end view thereof, withcmsegment of tiresome nut broken away.

Similar letters of reference indicate correspondingr parte. v

A is the shaft on which our device is arranged, and is held rmly in bearings in the frame B. 4

C C are hollow truncated-cone-shaped hubs, (their truncated extremities being` sct toward each other and are held in their required positions by the set-screws d d.

These hubs areprovided with T-shaped flanges E, either bolted to them or cast in one 'piece with them.

The pins F, held down Vby springs f, play through the flange and the end, c, of the hub C, as shown in the drawing. I

The screws on the shaft A are opposite rightrand-left screws, so that, as the shaft revolves, the Cono-shaped nuts G have a tendency to approach each other.

These nuts, as they advance within the cone-shaped hubs C, comeV in contact with the inner ends of the pins F, and push them out, until they come in contact with the inner surface of the barrel, which is placed upon the iianged conical hubs C. 'I

By these pins the barrel is securely held, the set-screws preventing` the hubs from beingdriven together closer than desired. i i

`-In using the machine, the barrel is first set up in truss-hoops.

It is then placed upon thc langed hubs, and secured in place by screwing up the nuts G, which force the pins F upon tho barrel, as before described, and is then made to revolve with the. shaft A..

When thus held, the outside of the barrel may be turned, and the ends crozed as desired.

We claim as new, 'and desire to secure by Letters Patent- The adjustable flanged cone-shapedhubs C, when provided with the sliding pins F and springs f in the angeE, in combination with the cone-shaped nuts G, and screwshaft A, as herein shown and described.
